Drip Irrigation - A watering technique that reduces water use by 20 - 50%, utilizing a series of hoses and small emitters or porous tubing to deliver small amounts of water to individual plants.  4, record 1, English, - porous%20tube

Subsurface drip irrigation is a variation of traditional drip irrigation where the tubing and emitters are buried beneath the soil surface, rather than laid on the ground or suspended from wires. The products being used today in subsurface drip irrigation come in three basic configurations : hard hose, drip tape, and porous tubing.... Porous pipe products emit water all along the length of the tubing. There are literally thousands of places per meter where water weeps out of the tubing. This design has shown resistance to plugging by roots. The disadvantage is its flow path is by far the smallest of the three configurations. This increases the likelihood of plugging by fine particles. It typically has the largest coefficient of manufacturing variability of the three configurations, which can be a major detriment because it prevents high distribution uniformities and high efficiencies.  5, record 1, English, - porous%20tube

Le goutte à goutte [...] permet de distribuer l'eau directement au pied des plantes, sans mouiller la partie supérieur (feuilles, fleurs, fruits). Il existe quatre techniques de goutte à goutte : le goutte à goutte mono fil : on ne pose qu'un seul goutteur ou un seul capillaire par plante ou par pot. Le goutte à goutte multitête : il s'agit d'une tête de distribution comportant 6, 8 ou 12 sorties. L'utilisation d'une gaine, un tube perforé tous les 30, 40 ou 50 cm. Les tubes poreux. L'eau est distribuée tout le long du tube du fait de la porosité du tube.  1, record 1, French, - tube%20poreux

Subsurface drip irrigation is a variation of traditional drip irrigation where the tubing and emitters are buried beneath the soil surface, rather than laid on the ground or suspended from wires. The products being used today in subsurface drip irrigation come in three basic configurations : hard hose, drip tape, and porous tubing.... With drip tapes, the tubing wall thickness from 0. 1 to 0. 5 mm(4-20 mils). The thinner materials are more commonly found in single season or throw away applications, typical of strawberry production. The heavier wall materials ranging from 0. 35 to 0. 50 mm(15-20 mils) are more commonly found in multi-year applications or where the extra strength is required due to stones or other problems identified at the field site.  3, record 2, English, - drip%20tape

Gaine. En irrigation, rampe perforée ou poreuse de faible épaisseur, servant à l'irrigation au goutte-à-goutte. Les gaines perforées ont une paroi extérieure perforée, à intervalles réguliers, de trous d'environ 0,5 mm de diamètre, servant à la distribution de l'eau. Elles sont soit simples, soit doubles (deux sections accolées).  3, record 2, French, - gaine%20perfor%C3%A9e

Drip Irrigation.... Water is delivered in small quantities under low pressure directly to... the root zone of the plants. You’ll need 1/2 inch polyethylene header pipe, and a roll of thin tape-like porous tubing. The header pipe connects to a garden hose and routes water through the garden. The pipe is placed either down the center or along one end of the garden. Small puncture holes are then made with a screwdriver into the header pipe at intervals corresponding to garden row. Eight-to ten-inch pieces of rubber connecting hose are then inserted into these holes. The other end of the connecting hose attaches to a length of porous tape. This tape is rolled out along each vegetable bed and cut to the same length as the row. Then end of the tape is then crimped to prevent water loss when the system is in use. Porous irrigation tape is best placed about three to four inches away from the base of the plants.  1, record 3, English, - porous%20irrigation%20tape

Les rampes aplatissables sont appelées des gaines qui peuvent être simples ou doubles. On distingue divers types de gaines : - gaines perforées [...] - gaines poreuses : la paroi extérieure, composée de fibres «non tissées», laisse suinter l'eau à travers des pores de quelques micromètres. Gaines perforées et poreuses ne sont utilisables qu'à de faibles pressions et ne peuvent convenir que pour des cultures annuelles (maraîchage, fleurs) en terrain plat.  1, record 3, French, - gaine%20poreuse
